ASSEMBLY
ASSEMBLY OF THE TXU-2, TXU-4 & TXU-8 CYLINDER ASSEMBLIES
1.
Clamp the housing (1) in copper-covered or leather-covered vise jaws with the end cap end
downward.
2.
Apply a non-permanent thread-locking compound to the threads of the cylinder gland (17). Use
the gland removal tool (41) to thread the bushing into the small central opening in the housing and
tighten until flush with the housing (1).
Note: TXU-2 does not have a cylinder gland.
3. Flip the housing (1) in the vise and install the seal insertion tool (40).
Note:
Lubricating the inside of
the insertion tool and the sides of the piston rod assembly and end cap will ease installation.
4.
Insert the piston (2) into the seal insertion tool (41), notched end leading and toward the link pin
hub, and tap into housing approximately 1”.
5.
Insert the end cap (7), swivel inlet toward the link pin hub, into the seal insertion tool (40), and tap in
until the piston (2) bottoms out against the housing (1).
6.
Install retaining rings (8), tapered edge leading into the grooves in the housing.
7.
Flip the housing in the vise and drive the piston (2) into the housing with a brass tap until the end
cap (7) seats in the retaining rings (8).
8.
Install the end cover (10), applying a non-permanent thread-locking compound to the end cover
screw (11) threads.
9.
Remove the housing from the vice and place on a soft block with the engraved side up.
10.
Install sliders (6), one on each side of the piston (2).
For TX-8 models:
Install sliders with the
cutout towards the piston. Align the holes in the sliders with the holes in the piston and the housing.
11.
Install slider pin (12) until flush with top slider.
12.
Apply moly grease to the face of the sliders and the notch in the piston.
13. Apply non-permanent, thread-locking compound to the threads of the cylinder, and install uniswivel
O-rings and uniswivel (USS for TXU-2 or USL for TXU-4 & 8), tightening uniswivel post screws (20)
in a cross pattern.
ASSEMBLY OF TXU-16 CYLINDER ASSEMBLIES
1.
Press the slider pin (12) into one of the sliders (6) until flush with one side. Install the pin through
the hole in the piston rod (2A) and press the remaining slider into the pin.
2.
Clamp the housing (1) in copper-covered or leather-covered vise jaws with the end cap end
downward.
3. Apply a non-permanent, thread-locking compound to the threads of the cylinder gland (17). Use the
gland removal tool (41) to thread the gland into the small central opening in the housing and tighten
until flush with the housing (1).
4.
Insert the piston rod (2A), threaded end leading, into the small cylinder gland in the housing. The
notch in the trailing end of the rod should be towards the retaining pin hub.
5.
Insert the piston cap (2B), hex end trailing, into the bore of the housing and use a socket to thread
and tighten the piston cap onto the piston rod.
